Property that qualifies for 1031 treatment is property you purchased with the intent of holding for productive investment use (not fix n flip). 

I have been interested in marketing rentals to medical professionals for awhile, but haven't done any deals like this yet. 

@Ian Ippolito great point on judicial/non-judicial. 

I am helping some friends with their non-profit organization that provides a place for families to stay while visiting someone at the local university.

.), but I have had some real challenges such as just yesterday had a tenant OD (and pass away) in a unit, as well as not one but two kidnappings last summer, a tenant who’s son got shot in the face in the parking lot, some stabbings, countless fights and arguments and cops at the building and of course the missed rent payments (tenant portion of course which is only $50-100), and much higher turnover rate than my non-section 8 units just because folks who can’t afford rent generally have less stable lives and move/ are involved in crime/ go to jail/ fall off the wagon/ have incidents of domestic violence/ revert to homelessness etc. more often than other tenant classes.

Also due to major medical bills my Ficos dropped to 700+- though after working with them my current ficos are under 800 and should be in the low/mid 800's again pretty soon!

Section 8 tenants are a lot like non-8 tenants in that some will respect your property and some won't.

If they did have such a list (they don't'), that list would only be useful if it contained personal, non public information on a borrower's payment/financial history, which would be illegal.

I like the class functions they you could segregate costs by unit, building, and even geographic locations, such as NY vs MA, through the use of classes, subclasses, down 10 levels.At the same time, I also did accounting on the side for a government funded non profit that that I use classes to segregate funding sources.

If a non REO, place a clause about utilities being turned on in the contract, affecting your time lines if it is not.When utilities will not be turned on, you need a heavy generator, air pressure test plumbing, etc.
